Doctor Know, short for Doctor Know-It-All, is a powerful sorcerer who frequents the fringe dimensions looking for lost souls and broken barriers. He has short, dark, curly hair and his eyes have purple pupils. He always wears his trademark purple and gold scarf and gray trench coat, but otherwise dressed in vintage clothing and has a strong liking for "geek" themed t-shirts. Wearing a gold wedding band on his left ring finger, he appears to be a man of African descent.
He operates out of a pocket dimension known as "Knowheresville", a bizarre realm that appears as an ever changing classic American small town. Knowheresville is populated by various benovelent alien beings, each of whom fills a role in the town such as police officer, milk man, nurse and short order cook. These beings don't seem to notice the changes in the town around them, or if they do it seems natural to them and they pay it no mind. The only reliable and constant location in the dimension is the Library, located in the exact center of the "town", where Doctor Know is said to live.
Doctor Know has been known to intercede in the affairs of mortals in various realities, but he tries to manipulate things from behind the scenes rather than taking a direct hand in them. He will always pass his great knowledge freely to those in need, though he tends to be long winded.
He is an enemy to the powerful beings known as Outsiders, and will go out of his way to hunt them and challenge their corruption of others.
